I have seen one of these with markings to suggest
that the pattern for the design came from a "Casey Jones". An almost
identical motor to those seen in the "T" class is pictured in a book
published in 1931, describing a range of "Casey Jones" products.

This may have been the motor. But as with the
"S"
series cars, the railways were great at knocking out their own
copies. These cars where built in the Islington Workshops,
Adelaide.

The Commonwealth Railways also had a car very
similar to this, but it was known as the "Victorian Casey Jones".
There is evidence of these being used on the Central Australia
Railway into at least the 1950s.

Large single cylinder two stroke engine, flat belt
drive with a sliding base motor to tension. Magneto ignition. The
cast wheels have a bolt on rim with separate hub. One wheel was
"free" to allow turning

There is evidence to suggest that these where
built for both the broad 63" and narrow 42" gauges. Car above is
narrow.
